Generalised Information and Entropy Measures in Physics [PDF]

open access: yesContemporary Physics, 2009
The formalism of statistical mechanics can be generalized by starting from more general measures of information than the Shannon entropy and maximizing those subject to suitable constraints. We discuss some of the most important examples of information measures that are useful for the description of complex systems.

Entropy as a measure of database information

[1990] Proceedings of the Sixth Annual Computer Security Applications Conference, 2002
An estimate of the information a database contains and the quantification of the vulnerability of that database to compromise by inferential methods is discussed. Such a measure could be used to evaluate the deterrent value of extant protection methods and provide a measure of the potential for inferential compromise through the use of one of the known

Minimum entropy and information measure

IEEE Transactions on Systems, Man and Cybernetics, Part C (Applications and Reviews), 1998
Kapur et al. (1995) introduced the MinMax information measure, which is based on both maximum and minimum entropy. The major obstacle for using this measure, in practice, is the difficulty in finding the minimum entropy. An analytical expression has already been developed for calculating the minimum entropy when only variance is specified.

Entropy Measures for Probabilistic Hesitant Fuzzy Information

open access: yesIEEE Access, 2019
The probabilistic hesitant fuzzy set (PHFS), which is remarkable in describing the practical condition, has attracted great attention and been applied to many areas. Although lots of achievements have been obtained, there are also some fields, such as the entropy measures with respect to the uncertainty of the information, have not yet been studied ...

New entropy type information measures

Proceedings of the ITI 2009 31st International Conference on Information Technology Interfaces, 2009
The target of his paper is to introduce new entropy type measures of information. The defined measure yields to an extension of the multivariate normal, the hyper multivariate normal ...

Information Entropy Model for Anonymity Measurement

2013 5th International Conference on Intelligent Networking and Collaborative Systems, 2013
Along with anonymous communications system being widely researched, anonymity measurement becomes more and more significant. However, there is still no desired mathematical model for this. In this paper, some necessary features for anonymity measurement model are analyzed and a dynamic model based on information entropy is proposed. Then some analyses,

On a generic entropy measure in physics and information

2009 7th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks, 2009
We define a generalized entropy that measures the evenness of the distribution of the real non-negative elements of a multiset X . The approach is to determine a comparison multiset R which is in a precise sense equivalent to X and which contains only one distinct positive element, whose multiplicity k then yields the desired measure.
